To all whom it may concern:

Be it known that ,1, ALVAH D. HADSEL, a citizen: of the United States,residing at .Wilkes-Barre, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inElevated Carriers, of which the following is a specification.

This invention relates to a. certain type of -elevated carriers adaptedespecially for use .with some of the parts in dilierent position.'

Fig. 3 is a side elevation, with certain parts in section, of the skipand parts associated therewith, and Fig. et is a plan view oi' thestructure of Fig. 3.

Throughout the following descriptionand l on the several ligurcs ofthedrawings similar parts are referred to. by like reference characters.

The apparatus includes a power frame or carriage 10, mounted fortransportation on any suitable form of runners indicated as wheels l1,the vdesign being for the power frame or carriage to be moved by anysuitable means along the lineof the operation. A standard 12 is rigidlyconnected to the main portion of the frame 10 and extends upwardlytherefrom. To the upper end of' the standard is attached a rigid truss13. The trusgrnaybe connected to the standard by means of pivots '13',so, that the end thereof distant from the standard may be moved slightlyup or down, depending upon the contour of the country operated upon. The

truss -13 is presumed to be of considerable i length, even as great astwo or three hundred feet, and is adapted to span the canal or ditchwhich is being dug. The outer end 13L of the truss `may be supportedupon a truck.

or 'fioat 14 of a character suited to the work being done. Said end may,rest directly upon the ground or it may be carried by a float which mayrest upon the surface of a body of water, practically the only essentialrequisite being that the truss 13 must be substantially rigid -andinclined downwardly from the pivot points 13.

Mounted upon the frame 10 are a plurality of independently operatedpower drums 15 and 16. A pair of cables 17 are connected. to the drum 15and extend thence upwardly and outwardly over a pair of directionpulleysc18 mounted upon the upper end of' the standard 12,` and thencesaid cables extend to the outer end 13a of the truss and are thereattached permanently at 17. The cables 17 between the pulleys 18 andpoint of attachment 17 are always parallel to each other and may or maynot be held in a substantially taut condition iso as to be parallel withthe truss 13, this condition 'depending upon the operation ot thedrum-15.

A skip 19, provided with a set of wheels 20, Ais'adapted to operate uponthe cables 17, the skip being designed to operate outwardly anddownwardly by gravity along the truss and over said cables when the sameare taut..

Specification of Letters Patent. i Patented-J 1i, 19110.

The skip has connected to its front end,

however, a cable 21 which extends thence upwardly over a directionpulley 22 connected centrally to 'the top .ot the standard 12 and thencecable 21 extends downwardly and is wound upon the drum 16. When thepower isapplied to the drum 16 to wind u the cable 21, theskip willbedrawn toward the power frame and upward toward the top of the standard12. The skip comprises two vprincipal partst-a main frame 23 and abucket 24. Said two parts are pivoted together at the rear end of theskip by means of the axle 20 of the rea-r wheels, and the bucket portionis adapted to swing downwardly with respect to the frame 23 unless itis' held upward by some means. As a convenient means for locking thebucket 24 up within the frame, I may employ a bail 25,

pivoted upon the front axle 2G, and provided with one or more downwardlyprojecting arms 27 havlng notches 27 adapted to .en-

bucket. The forward forward end oit tbe end ot the bail is suiiicientlyheavier than the other portion to insure the prompt engagement or" saidlugs 28 when the same are brought into position to oe engaged thereby.The downward movement, however, of said forward end 25 is limited byengagement with the traine at the points 23. rlhe traine 23 is providedwith an outwnrdly extending flange 23a which lies just beneath the trackcables 17 and prevents displacement ot the carrier wheels 2,0 therefrom.

A trip cznn 29 is connected to the cables 17 at any point where it isdesired to dump the bucket, said connection being made by adjustableclamps 29. Said cani is so formed gage ings 28 on the and disposed. asto receive the forward endor point 25 of tbe locking bail when the skipis drawn upward'toward the top ot' the standard. The said end ot thebail riding up the incline of the cam will cause the lugs 28 to bereleased from the arms *27 and permit the bucket with its contents toswing downwardly around the axis 20.

The operation ot the device may be substantially as followsz' "With thecables i7 taut, the skip 19 will gravitate downwardly lthereon towardthe outer endl 13 of the its lili

' operated upon so truss as liar ,as will. bev permitted by theslackening of the cable Q'ifpresumably to or over the point where anexcavation is to be made, Upon slackening the cables 17 the skip willthen be lowered so that the bucket will strike the earth, cans-sing itto be lifted peet to 'the traine 2?) and bringing the lugs 528 thereofinto interlocking engage- 27. lWith the cables 17 i, ip 'will be drawi'iby the dri i6 und crible S61 toward the poi ironic l0, the cutting edge211i of tbc bucket cutting; or diggO J the earth and filling thecarri-er. [it tnis time, both the cable El and *"scli; cebies be it tbccables l? may be Upon continued. dratt upon. the skip, the will bebrought, into dumping position as above described and the operatior maythen ne repeated. :iside from the ion ot the drums in the manner aboveibed the operation of the carrier is substantially automatic throughout.
